Application filed May 12, 1921. Serial No. 468,876.

T 0 aZZ whom it may concern:

Be it known that I, HANS P. Hanson, a citizen of the United States, and a resident of Cambridge, in the county of Is'anti and State of Minnesota, have invented a new and useful Improvement in Window Silencers, of which the following is a full, clear, and exact description;

My invention relates to improvements in anti-rattling devices for windows and more particularly to such devices for windows embodied in automobiles and other vehicles of the inclosed' type, and it consists in the combinations, constructions and arrangements herein described and claimed. I

An object of my invention is to provide a device of the character described that is adapted to be applied to an enclosed automobile of an ordinary type and has means for engaging the glass pane of a window embodied in the automobile to prevent the vibrations of the glass pane and thus eliminating noise ordinarily caused by the vibrating or rattling of the glass pane.

A further object of my invention is to provide a device of'the character described that can be applied to an automobile of an ordinary construction without any change in the usual construction of the latter being required. 1

A further object of my invention is to provide a device of the character described that has means arranged for instant movement into engagement with a window to prevent vibrations of the glass pane thereof or out of engagement. withthe window to permit adjustment of the window in the usual manner.

A further object of my invention is to provide a device of the character described that is simple in construction and operation, not likely to get out of order easily, and thoroughly practical commercially.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a view, showing the use and application of the device,

such as indicated at 3, and the glass pane L or other transparency is held by a frame for movement vertically in a slot 5 in a sill 6, whereby the wmdow 3 may be positioned with the greater portion of the glass pane 4 either above or below the plane of the upper surface of the sill 6. The parts described so far are ordinary in construction and form no part of my invention except in so far as they cooperate with the parts about to be described.

It is well known that an objectionable noise is caused in an automobile enclosure window on account of the vibrations of the glass pane of the window. Such vibrations may be due to a looseness or" the glass pane in its frame or on account of play between the frame supporting the glass pane and the parts of the enclosure frame contacted thereby. In carrying out my invention, I provide a disk 7 made of compressible resilient material, such as rubber. The disk 7 is formed with an opening 8 positioned off center so that the disk 7 is mounted eccentrically on a spindle 9 that is secured to the sill 6 to project vertically above the surface of the latter at a spaced distance from the adjacent edge of the slot 5. The spindle 9 may be a screw threaded into an opening 10 in the upper wall of the sill intermediate the length of the latter. A lower bearing plate or washer 12 is disposed between the disk 7 and the sill 6 andis formed with upstanding prongs 13 pressed into the contiguous side of the disk 7. An operating member 14 has the form of a disk mounted on the spindle 9 and superposed on the disk 7 so that downwardly bent prongs 15 are pressed into the upper side of the disk 7 and the operating member 14, the disk 7, and the lower bearing 12 will rotate as a unit about the spindle 9. The operating member 14 has an integral extension 16, constituting a handle adapted to be grasped conveniently to permit adjustment of the eccentric disk 7 with respect to the glass pane 4:.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood; When the eccentric disk 7 is, in the position indicated by the full lines in Figure 2, the glass pane 4 will not be engaged thereby and consequently the window 3 may be moved vertically'as desired; When the handle 16 is grasped and the disk 7 moved into the position indicated by the dotted lines in Figure 2, a stress will be placed on the glass pane 4 that will tend to move the latter away from the spindle 9. Consequently, play between the pane 4 and its frame and between the latter and the parts of the enclosure 2 contacted thereby is prevented. Since the disk 7 is formed of rubber or like compressible resilient. material, the glass pane 4- will not be injured on account of the engagement'of the disktherewith. The disk will remain in the position indicated by the dotted lines in Figure 2 since it will be compressed toward the spindle 9when moved into the position shown.

Obviously, many adaptations and modifications of the form of the device illustrated in the accompanying drawings may be provided without departing from the spirit and scope of'my invention as described in the foregoing and outlined more particularly in the appended claim and I therefore consider all such modifications and adaptations as my own. 1

v I claim: 7

The combination with a window sill having a slot therein, a window frame slidably disposed in the slot, and a glass carried by said frame, of a screw carried by said sill, a

resilient disk eccentrically mounted on said screw, plates concentrically mounted on said screw and being disposed on both sides of said disk said lates havin inte 'ral ron' s adapted to engage with said disk, and a handle carried by one of said plates.
